Talk about a bad case of cell phone addiction. Chinavasion describes this as the ultimate hands-free device, and for good reason: It's a tiny microphone designed to be embedded in the teeth.

If we weren't told otherwise, we'd swear this was an April Fool's prank. But the "Bluetooth Dentacom" is apparently for real, a "composite resin filling" that will "pick up sound and vibrations from your mouth to produce incredibly clear sound," according to GeekAlerts.

That's not spinach

But take note of the distributor's advice: "All dental work should be performed by a qualified dentist. Chinavasion does not take responsibility for injury resulting from the installation of this product." We'll stick with the speakerphone for now.
